rbd: introduce rados block device (rbd), based on libceph
The rados block device (rbd), based on osdblk, creates a block device that is backed by objects stored in the Ceph distributed object storage cluster. Each device consists of a single metadata object and data striped over many data objects. The rbd driver supports read-only snapshots.
